Here, the effects of a newly designed ferroelectric oxide synthesized by solid reaction, barium strontium titanate [BST (85/15)] (Ba_0.85Sr_0.15TiO₃), on the carpet shell clam Ruditapes decussatus were investigated. These clams were exposed to four concentrations of BST (85/15) nanoparticles (0.001, 0.01, 0.1, and 1 mg.L⁻¹), and BST (85/15) was absorbed by R. decussatus in an exposure intensity-dependent manner. Measurements of clearance rate and biomarkers confirmed that the nanoparticles significantly affected the health of clams in an organ-dependent manner. Interestingly, BST (85/15) nanoparticles stimulated acetylcholinesterase (AChE) activity in the clams, suggesting their usefulness as antagonists of AChE inhibiting pollutants. These findings demonstrate the suitability of R. decussatus as a test organism to provide a framework for understanding the toxicological effects of these newly designed ferroelectrics. Moreover, concentrations of BST (85/15) < 0.1 mg.L⁻¹ could be good alternatives to lead-based ferroelectric oxides and could be sustainable tools for use in electronic applications.

在这里，研究了一种新设计的通过固相反应合成的铁电氧化物，钛酸钡锶钛酸盐[BST（85/15）]（Ba _0.85 Sr _0.15 TiO ₃），对地毯壳蛤Ruditapes decussatus的影响。将这些蛤暴露于四种浓度的BST（85/15）纳米颗粒（0.001、0.01、0.1和1 mg.L ^-1），BST（85/15）被Decussatus吸收。以依赖于曝光强度的方式。清除率和生物标记物的测量结果证实，纳米颗粒以器官依赖的方式显着影响了蛤类的健康。有趣的是，BST（85/15）纳米颗粒刺激了蛤中的乙酰胆碱酯酶（AChE）活性，表明它们可用作抑制AChE污染物的拮抗剂。这些发现证明了拟南芥R. decussatus作为测试生物体的适用性，为理解这些新设计的铁电体的毒理学作用提供了框架。此外，BST（85/15）<0.1 mg.L ^-1的浓度可能是铅基铁电氧化物的良好替代品，并且可能是用于电子应用的可持续工具。
